# unregister-host

## Description

Unregister a host

Delete a host from the state file. This command will not connect to the host, nor will it perform any operations on its nodes.

To destroy an existing cluster  and deploy a new one by deleting all data, deleting all nodes, uninstalling all `singlestoredb-server` packages, and unregistering all hosts, use [sdb-deploy destroy-cluster](https://docs.singlestore.com/db/v9.1/reference/singlestore-tools-reference/sdb-deploy-commands/destroy-cluster.md).
